Evaluación preliminar de la sustentabilidad de una propuesta agroecologica, en el subtrópico del altiplano central de México (Preliminary assessment of the sustainability of an agroecological proposal in the the central highlands of Mexico)Frente al creciente interés del uso de enfoques sistémicos para la evaluación de sustentabilidad como herramienta de toma de decisions, los autores realizaron la evaluación de una finca universitaria ubicada en el subtrópico del Altiplano Central de México. En la primera fase del estudio (2004) se realizaron la caracterización, el diagnóstico y la evaluación inicial. Se identificaron y priorizaron los principales problemas, para los cuales se derivaron propuestas de solución bajo un enfoque agroecológico. Full resource not available online |
Evaluación de la regeneracion de Acacia decurrens, Acacia melanoxylon y Ulex europaeus en áreas en proceso de restauración ecológica (Regeneration study of different Acacia species)Esta investigación busca establecer la dinámica de regeneración de Acacia decurrens, Acacia melanoxylon y Ulex europaeus dentro del proceso de restauración ecológica adelantado en el Parque Nacional Enrique Olaya Herrera, por el Jardín Botánico José Celestino Mutis, Bogotá, Colombia. En las áreas con presencia de individuos arbóreos de Acacia decurrens y Acacia melanoxylon se presenta expresión del banco de semillas con formación periódica de la capa de hojarasca que detiene o desvía el proceso sucesional.

Caracterización sucesional para la restauración de la reserva forestal Cárpatos, Cundinamarca, Colombia (Characterization of the succession for restoration in Colombia)EspañolAntecdentesCon base en la caracterización florística y estructural se analizaron cuatro etapas del proceso de sucesión secundaria, dentro de una matriz de vegetación que había sido objeto de pertubación (185 ha) en la Reserva Forestal Cárpatos, localizada en la cordillera Oriental, entre 2600 y 3000 msnm, con el objetivo de contribuir a la preparación de un protocolo de restauración.

Intensive Tree Planting Facilitates Tropical Forest Biodiversity and Biomass Accumulation in Kibale National Park, UgandabackgroundThis study investigates how intensive planting affects tropical forest regeneration and biomass accumulation in reforested sites in Kibale National Park, Uganda. The study assessed species richness of naturally regenerating (i.e. non-planted) species in the park and compared the biomass accumulation of planted versus naturally regenerating trees in sites replanted by the Uganda Wildlife Authority.

Effects of Canopy Cover and Understory Environment of Tree Plantations on Richness, Density and Size of Colonizing Woody Species in Southern EthiopiabackgroundThis study investigates the effects of canopy characteristics and associated understory environmental factors of tree plantations on native woody species colonization in two broadleaved and two coniferous plantations in southern Ethiopia. The plantation forests investigated are surrounded by dry Afromontane natural forest. Available with subscription or purchase |
Establecimiento de un sistema silvopastoril mediante las especies Alnus acuminata H.B.K. y Acacia decurrens Willd y respuesta al empleo de organismos rizosféricos en San Pedro (Antioquia)EspañolAntecedentesEL monocultivo y uso excesivo de fertilizantes en pasturas del trópico alto, han desencadenado problemas ambientales así como un inadecuado manejo sanitario y nutricional del ganado.

Fire Control as a Simple Means of Promoting Tropical Forest RestorationbackgroundThis study investigates whether or not fire exclusion allows grasslands to regenerate to forest in a timeframe suitable for reforestation efforts. The researchers compare tree species richness, dbh, diameter at ground height (DGH), and total woody biomass accumulation in 2 plots that have been protected from fire. They measure the size and amount of above ground biomass in plots that have been protected from fire for 12 and 32 years respectively in Kibale National Park, Uganda. Open access copy available |
A Comparative Assessment on Regeneration Status of Indigenous Woody Plants in Eucalyptus grandis Plantation and Adjacent Natural ForestbackgroundThis study investigates and compares diversity, density and species composition of naturally regenerated woody plants under Eucalyptus grandis plantations and the adjacent natural forest in southwestern Ethiopia. research goals & methodsVegetation data was collected from 40 sample plots, 20 in natural forest and 20 in plantations. Within the plots plant species were identified, DBH of all trees measured using a caliper; total heights of larger trees were measured using hypsometer. Available with subscription or purchase |
Survival and Growth of Seedlings of 19 Native Tree and Shrub Species Planted in Degraded Forest as Part of a Forest Restoration Project in Madagascar's HighlandsbackgroundThis study compares the survival rates of 19 native tree and shrub species grown in a forest restoration project in Madagascar’s highlands. The study results are used to compare the survival of relatively short seedlings compared to relatively tall seedlings for all species combined in order to test the importance of seedling size for restoration.

Analysis of the "Shelter Tree-Effect” of Natural and Exotic Forest Canopies on the Growth of Young Podocarpus falcatus Trees in Southern EthiopiabackgroundThe potential for plantations of fast-growing non-native trees to create suitable habitat for regeneration of native plant ecosystems has gained attention in the scientific literature. Previous studies often focus on the plantation species’ impacts on soil, but this study in the Munessa-Shashemene forest of Ethiopia proposes that light factors may be important as well. In this forest, native Podocarpus falcatus saplings actually perform better under the canopy of planted non-native Pinus patula and Eucalyptus saligna trees than in native forest, and this study hypothesizes that varying patterns of irradiance and sunflecks may explain this phenomenon.
